swapping out auto boxes in mk3

[hartster]

I don't have any experience of MK3 autos.

I need to find a replacement for a DNR code auto trans into a '98 ADR engined MK3.

I have been offered various options. Will, for instance, a DLL code box fit / work out w.r.t. ratios etc?

I'm battling to find a chart of ratios on the net, like the ones you get for 020 manual boxes. Anyone got a link?

Suggestions appreciated, wanna help out my mate but also wanna get the right box...
